Chrysanthemum plant named ‘Zanmutrick’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Zanmutrick’, characterized by its upright, outwardly spreading and uniformly spherical plant habit; moderately vigorous growth habit; freely branching habit; dense and full plant habit; dark green-colored leaves; uniform and freely flowering habit; long flowering period; decorative-type inflorescences with ray florets that are brilliant yellow in color; and good garden performance.

Botanical designation: Chrysanthemum x morifolium.

Cultivar denomination: ‘ZANMUTRICK’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum x morifolium, commercially referred to as a Garden Mum and hereinafter referred to by the name ‘Zanmutrick’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Rijsenhout, The Netherlands. The objective of the breeding program is to create new uniform spherically-shaped and freely flowering Chrysanthemum plants with unique and attractive ray floret coloration.

The new Chrysanthemum plant originated from a cross-pollination in February, 2014 of a proprietary selection of Chrysanthemum x morifolium identified as code number 10-011073, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum x morifolium identified as code number 22.2254, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rijsenhout, The Netherlands in July, 2014.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Rijsenhout, The Netherlands in September, 2014. Asexual reproduction by vegetative terminal cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Zanmutrick’. These characteristics in combination distinguish ‘Zanmutrick’ as a new and distinct Chrysanthemum plant:

-   -   1. Upright, outwardly spreading and uniformly spherical plant         habit; moderately vigorous growth habit.     -   2. Freely branching habit; dense and full plant habit.     -   3. Dark green-colored leaves.     -   4. Uniform and freely flowering habit.     -   5. Long flowering period.     -   6. Decorative-type inflorescences with ray florets that are         brilliant yellow in color.     -   7. Good garden performance.

Plants of the new Chrysanthemum can be compared to plants of the female selection parent. Plants of the new Chrysanthemum differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Under natural season conditions, plants of the new         Chrysanthemum flower about four weeks earlier than plants of the         female parent selection.     -   2. Plants of the new Chrysanthemum have larger inflorescences         than plants of the female parent selection.

Plants of the new Chrysanthemum can be compared to plants of the male selection parent. Plants of the new Chrysanthemum differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Ray florets of plants of the new Chrysanthemum are brilliant         yellow in color whereas ray florets of plants of the male parent         selection are pink in color.     -   2. Inflorescences of plants of the new Chrysanthemum do not have         disc florets whereas inflorescences of plants of the male parent         selection have disc florets.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum x morifolium ‘Zanmugolmine’, disclosed in U.S. Plant Pat. No. 22,618. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Zanmugolmine’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are twice as large as plants         of ‘Zanmugolmine’.     -   2. Under natural season conditions, plants of the new         Chrysanthemum flower about four to five weeks earlier than         plants of ‘Zanmugolmine’.     -   2. Inflorescences of plants of the new Chrysanthemum have fewer         ray florets than inflorescences of plants of ‘Zanmugolmine’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph (FIG. 1) comprises a side perspective view of a typical flowering plant of ‘Zanmutrick’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 17-cm containers in an outdoor nursery in Rijsenhout, The Netherlands under natural daylengths during the summer and autumn and under cultural practices generally used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 15° C. to 25° C. and night temperatures ranged from 8° C. to 15° C. Plants were 18 weeks from planting when the photograph was taken and the detailed description was taken on plants from 15 to 20 weeks after planting. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
